ID for the midge. Ovipositing on fireweed buds. Also pictured is a parasitic wasp, likely Platygastrinae, ovipositing as well. Nature's checks and balances. I observed the midge ovipositing on many of the flower buds. Wasps kept flying in and visiting the buds she went to but were extra concentrated on this one bud. Lots of wasps were hanging out on the underside of the leaves. Visited the next day and saw several more of the same species of wasp visiting this exact bud, but no midges were present. Edit: 06/29/2024 this is the only flower bud to have developed a gall.

Gall on golden chinquapin (Chrysolepis chrysophylla)(the reddish one).
Also spikey fruit and old flowers.
If you zoom in, there are lots of small round galls blending in, in addition to the pea-size reddish one.

After a minute or so in the field, sharp-eyed @alice_abela spotted the inconspicuous little leaf gall about 2/5 the way up the leaf at left in the 1st photo here (just below the sinus of the largest lobe).

A higher-res view of that leaf gall appears in the 2nd photo; and of the stem gall in the 3rd photo.

The other photos show the underside of the leaf, and other views of the same leaf & stem galls...together with higher resolution crops. As far as I know, these were the only two types of galls we (Joyce, Alice, & I) found on the Palmer Oaks (see iNat obs here) off the old jeep road to Alpine Mine across the canyon from Clear Creek Road.

I'm speculating that the leaf gall & stem gall here may represent the associated (sexual) "spring generation" and (agamic) "fall generation" galls, respectively, for the undescribed cynipid species on Quercus palmeri whose stem gall I've referred to as the "Chef's Hat" or "Hot Air Balloon" gall in the recent posts below:

https://www.inaturalist.org/observations/211291919
https://www.inaturalist.org/observations/211303640
https://www.inaturalist.org/observations/211327036

https://www.inaturalist.org/observations/211336373
https://www.inaturalist.org/observations/211312302

The hypothesis is, again, only speculation at this point...and presumes among other things that this undescribed species indeed undergoes alternation of generations (though not all Cynipini do). But note that there are a number of cynipid species that have a sexual spring generation leaf gall followed by an agamic summer/fall generation stem gall — for instance: Bassettia ligni; Disholcaspis cinerosa (scroll down to 2nd & 3rd paragraphs under "Gall Wasps" here); and also Heteroecus dasydactyli and H. pacificus per the discussions on pp. 134-135 and pp. 137-138, respectively, of Russo(2021).

On 10/3/74 James Griffin vouchered a discovery of Quercus palmeri in the Clear Creek area of San Benito County. At that time this was a new, isolated, northerly station for this unusual species. Griiffin returned about 3 weeks later with his botanist friend and CA oak maven John Tucker, and together they collected a number of additional vouchers. At that time Q. palmeri went by the name Q. dunni (after the remarkable late-1800's naturalist & collector George Dunn, see Jepson's brief bio here). Later Griffin & Tucker published a 1976 Madroño note on the newly discovered station. Motivated by the above, and a prior interest in this species, I was eager to look for these Palmer Oaks...and joined Joyce Gross & Alice Abela to search for them, almost 50 years after Griffin & Tucker's voucher collections.

After planning and walking a route with a number of promising point locations suggested by the Madroño note & voucher labels, we seemed to have struck-out on our "best candidate sites" and were becoming somewhat discouraged. But crossing a creek after the road we were on faded out, Joyce came upon a smaller trail following the SW side of the creek, and within a few hundred feet there were 3 or 4 clumps of Palmer Oaks growing on the steep bank above the trail :-). Note that zooming-in on the iNat inset map above, the observation icon appears to the NE of the trail shown there...but that's an artifact of errors in either my camera's GPS reading, the rendering of the trail on the map, or both. The rough location is correct, but the trail follows the SW side of the creek there...and the Palmer Oaks are rooted along the eroding upper edge of the tall bank just SW of the trail.

Palmer Oak is thought to be a relict species that had a more widespread and continuous distribution in Pleistocene and Pliocene times. Except for a few areas in southern California, northern Baja California, and Arizona (see SEINet map here), nowadays it is usually found in small isolated stands of a few individuals, which are often clonal groupings...and these stands are typically many miles apart (e.g. ten, twenty, or much more!). One particular clonal colony growing high on a granitic summit in the Jurupa Hills of Riverside County, CA has been estimated to be 13,000+ years old in this 2009 paper.

The plants here were growing in 3 or 4 "clumps" of scrub to small tree-like stature — each with one to several small, clustered, multiple trunks. They appeared less clonal in growth form than other Palmer Oak groupings I've seen...but may have been clonal. I have no idea how old these plants currently are, but they may have difficulty persisting for a truly long time into the future at this site — as their roots are being undercut by erosion of the bank above the old jeep road/trail and adjacent creek. This may be exacerbated in part by human impacts...recent motorcycle tracks were apparent, and a large branch had been cut off and was lying by the trail. (Some branches were overhanging the trail...and Palmer Oaks are notoriously rigidly-branched with leaves that are viciously stiff & spine-margined!)

In addition to the Jepson eFlora treatment for Q. palmeri, more info is available on the SEINet page here.

Well, this may be Andricus occultatus. The bud is deformed. There is obviously more than one gall in the bud--at least 4 exit holes on the top of the bud. I found a larva inside, which would mean at least 5 chambers.

On coast live oak. I think these are galls - but I suppose they could be new growth. [edit: they are in fact galls]. However, they don't look like buds I'm familiar with, and I only found these on one tree [edit: after multiple re-visits, I found these on two trees]. This tree had a couple old Amphibolips quercuspomiformis, but the spring form of that gall is entirely different than this.

See https://www.inaturalist.org/observations/148539708 for what may be old forms of this gall, found nearby on the same tree.
